On the board, free cells are represented by <code>&#39;.&#39;</code>, white cells are represented by <code>&#39;W&#39;</code>, and black cells are represented by <code>&#39;B&#39;</code>.</p>\n\n<p>Each move in this game consists of choosing a free cell and changing it to the color you are playing as (either white or black). However, a move is only <strong>legal</strong> if, after changing it, the cell becomes the <strong>endpoint of a good line</strong> (horizontal, vertical, or diagonal).</p>\n\n<p>A <strong>good line</strong> is a line of <strong>three or more cells (including the endpoints)</strong> where the endpoints of the line are <strong>one color</strong>, and the remaining cells in the middle are the <strong>opposite color</strong> (no cells in the line are free).
